REFLANGEKiT® Concept

REFLANGEKiT® concept is based on a double shell system that encapsulates the leaking flange. The first shell made in PVC will cover and protect the flange and collect SF6 leaks. The second shell made in PET will contain 3X specific resin. An exhaust valve allows the gas getting out during resin injection. After overnight curing of resin, the valve is closed and sealed.

Thanks to this original system, flange and bolts are protected during resin injection and disassembly. The product can be easily removed without damage.
